> My guess: pulling tens of terawatts of energy out of the atmosphere will effect the climate.
Nobody is pulling anything *out* of anything. All they are doing is *moving* it.
As the Sun heats the surface, the surface heats the air, the air moves to carry the heat to places that are cooler.
As the wind blows it heats the environment due to conduction, radiation, and friction. The energy of the Sun has been moved from warmer to cooler and finally, ultimately, it is radiated back into space.
As the turbine is powered by the wind and generates electricity, the air is cooled, the electricity is transported elsewhere and the energy is ultimately dissipated as heat. Same net result, just a different distribution of the Sun's energy across the surface of the planet. Will it make a difference in the climate? Only locally as places downwind of the wind-farms will be cooler and less windy than otherwise and the places that consume the energy will be warmer than otherwise.
